Tyre pressures for Ethiopia
Greetings all tyre pressure experts (I know you're out there)!
We have a heavy Landy with BFG A/T tyres. Official tarmac pressures are 48/53 psi, and for dirt roads, two thirds of that. Now, we met some Brits the other day who said they followed local advice to pump their tyres up to 60 psi for the famously jagged roads of Ethiopia, the theory being that they would flick the sharp stones out of the way. They said they got no punctures. However, having suffered two punctures on Namibia's gravel roads at tarmac pressures, we're not so sure... However one thing we do observe with our tyres is that at reduced pressures the sidewalls do bulge, making easy prey for tall jagged rocks.
What should we do? All opinions, informed advice, witticisms welcome.
